No sir lack of 02s would just set off a check engine light it wouldn't flash. And you need front 02 sensors those are the upstream sensors that tell the computer what your air/fuel is. The rear 02s are the down stream sensors and are only there to compare data from the front two so it knows how efficient the cats are. You can have the rear 02s turned off with a tune and not have any ill effects , the upstream sensors have got to be there or the car goes into limp home mode... and the computer defaults to a rich mixture for engine safety purposes.
